Distributed Denial of Service (DDoS) attacks have existed for almost as long as the commercial web itself, the attack could cause the attacked target millions of loss revenue and sometime irreversible damage in reputation and customer trust. A10 Threat Protection System (TPS) provides DDoS mitigation solutions that works well with the open source and commercial partners.
